Performance enhancement refers to the use of various methods or substances to improve an individual's physical or mental abilities. This can include practices like training regimens, nutritional supplements, and psychological techniques aimed at boosting overall performance in sports, academics, or other competitive fields. In the context of sports, performance enhancement often involves the use of steroids, stimulants, or other drugs that can increase strength, speed, or endurance. While some methods are legal and accepted, others may be banned by organizations like the World Anti-Doping Agency due to ethical concerns and health risks associated with their use.
